NEW DELHI: Finnish telecom gear maker Nokia said that it has completed the world's largest modernization of a Home Location Register (HLR) database for Vodafone India.

The modernisation will help Vodafone improve customer experience and improving efficiency.

Further, the increased network resiliency will help Vodafone recover quickly in case of natural disasters.

"This is a big step towards delivering the Vodafone SuperNet experience to our customers. We believe we have executed the world's fastest and largest subscriber database migration without any network or services disruption," Vishant Vora, Director - Technology, Vodafone India, said in a joint statement.

"Nokia has once again done a commendable job in executing this complex and significant program ahead of schedule," Vohra said.

The number of database hosting nodes was also reduced from 46 to 12, improving efficiencies, enhancing performance and optimizing costs.

"As operators are focusing on making their networks more agile and subscriber-centric, we are providing our customers with solutions to deliver a superior experience. This program is the result of a strong and enduring relationship with Vodafone India," Sanjay Malik, Head of India Market, Nokia, said in a joint statement.

As part of the project, Nokia implemented its Subscriber Data Management (SDM) solution, which features Nokia's One-NDS (Network Directory Server), thereby consolidating network-related subscriber data into a single unified platform to be shared across multiple applications.

Nokia's Systems Integration Services team seamlessly migrated the HLR database without disruption to Vodafone India's network and its 200 million subscribers, efficiently meeting a challenging deadline with the highest quality.

Nokia's SDM technology's geo-redundancy feature ensures that the subscriber database of one location is backed-up in the HLR of another in case of any incident like a network upgrade or natural disaster - delivering a seamless network experience and ensuring business continuity for the Vodafone SuperNetTM.

Nokia offers the most complete SDM solution and portfolio of dataless applications, with more than 280 deployments (including more than 200 LTE deployments), serving almost five billion subscriber licenses worldwide.
